Strengthening behavior of composite containing discontinuous reinforcement is strongly related with load transfer at the reinforcement-matrix interface. One of the difficulties of fabrication of carbon nanotube (CNT) reinforced aluminum (Al) matrix composites is poor wettability. Ball-milling technique has been selected for dispersion of CNT in the Al matrix and the composite powders consolidated by hot-working such as hot-rolling and hot-pressing. The composites containing well-dispersed CNTs show much enhanced properties than monolithic Al. On the other hand, the Al/CNT composites fabricated by ball-milling and hot-working may have strong interface with the Al matrix by mechanical interlocking, because Al has poor wettability with carbon. With the aim of improvement wettability, we select titanium (Ti) to form relatively strong bond with the dangling branches of carbon atoms in CNT. Improved interfacial bonding may contribute to strengthening efficiency compared to Al/CNT composites.
